Description

The Ksport Dualcomp 4-piston rear big brake kit is engineered as an all-in-one dual caliper solution, specifically beneficial for drifting and rally racing applications. This innovative system utilizes a single 4-pot caliper, cleverly dividing its functionality: two pistons manage the primary foot brake, while the other two are dedicated to the handbrake system, each operating on its own independent circuit. Constructed for a seamless integration, this kit is designed as a complete bolt-on package, requiring no modifications for installation. It includes everything needed: 4-piston calipers, lightweight two-piece floating brake discs, SC5 Street Pads optimized for street and occasional track use, a polished titanium handbrake cylinder and lever, and all essential mounting components and hardware. The calipers can be customized with a wide array of painted or premium high-polish finishes, including Silver, Gold, Titanium, and an extensive range of custom colors. The kit features CNC-machined carbon steel caliper brackets to ensure proper fitment onto the OEM caliper bracket locations, accommodating the larger Ksport calipers. This Ksport Dualcomp kit is compatible with the 1987-1989 Toyota MR2 models. Ksport Big Brake kits are built to order, and customers should anticipate a production and delivery lead time of 4-6 weeks. Slotted rotors are recommended for track use, while Cross Drilled rotors are suggested for daily driven vehicles due to better cooling.
